A lady that runs a country store in Vermont gave me this and said to use it to unlock the jaws of my pitbull if she bit somebody by sliding in between the teeth and twisting, but I doubt that would work, and besides Sasha dog is a sweetheart, she would never hurt anyone on purpose.
The country store is cool as well, and the vampire slaying stick was a complimentary gift.
Visit the store in Quechee, Vermont! https://m.facebook.com/Route4CountryStore/
Dogs with big, square heads and large ears (like the Saint Bernard) are the best at hearing subsonic sounds.
Cool, thanks for the info.
